Mojo function

async_copy_wait_all

async_copy_wait_all()

Waits for completion of all committed cp.async-groups.

This function blocks execution until all previously committed cp.async-groups have completed their memory transfers. It provides a barrier to ensure all asynchronous copies are finished.

Notes:

• Only supported on NVIDIA GPUs.
• Maps to the cp.async.wait.all PTX instruction.
• Ensures all outstanding asynchronous transfers are complete.
• More coarse-grained than async_copy_wait_group().
